TO WHOM IT MAY CON CERN: i

Be it known that I, JULIUS WOOD, of Smyrna, in the county of Chenango, State of New York, haveinvented anew and improved machine for unloading hay' or straw, 'to be called a"Hay-Un1oader; Yand I do hereby declare that the following is a full and exactv description of the construction and operation of the saine, referencebeing had to the annexed drawings.

i A A A are hooks madeof round iron or steel rods. According to the experiments which I have made, the hooks should be made of five-eighths inch iron, or about that size. To make a pair of hooks,'take a rod of the required diameter and vabout three feet long, and sharpen both ends. Then double them in such a way as to make an eye, as shown at a, Figure Then the ends are bent into a hook, very much in shape like/ai iish-hvook;

but the pointsshould be ve or six inches or more apart. All that is necessary in regard to the sha-pelis' that they should be of such form as to hold on to the hay while drawing directly upon the eye. B BB are ropes, which are attached to the'hooks A A A at theveyes a a a in any convenient, manner, and the other ends are attached to the head C C. The ropes should be from eight to fifteen feet long, for reasons which will hereafter appear. The headC C may be ofA any convenient length, say three or four feet long. The head may be wholly dispensed with.` by substituting for it a large iron ring, into which the ropes may berfastened; but from experiment'I am satisiied that the ropes may be more easily keptfrorn tangling by the use of a head-piece three or four feet long than by the use of the ring, and hence is preferable; but I claim any'device, whether ring or bar, which answers the purpose of a headpiece. The ropes are passed through holes in the hcad-piecc, and knots tied in their ends, or otherwise fastened to the head-piece. In this way the lengths of the ropes are easily adjusted. Three ropes are all that are necessary for one machine, andiin some cases two would answer. An eye, b, is fastened to the Ahead C C, te which the rope D is fastened in any convenient manner.

The .Mcm-ner of Using.

It must be observed that whatever improvements may hereafter be made upon the machine, it is not intended, in its present form, to lift hay or straw, but to roll it oil'. Itis therefore to be used for unloading hay into a bay or low mow or onto the bottom of a stack. For these purposes I claim great advantages over anyherctofore known device. To use it, remove the rope D, and place the machine upon the rack before the load is placed on. The outsidehooks should be placed near the ends ofthe rack and the other midway between. Then put the load on, covering the ropes and hooks, and drive to the place where it is to be unloaded. The load may now be rolled offE simply, or it may be rolled oil and back some distance. It' it be desired to simply roll it oil', the hooks must be fastened into the hay just above the rach. 'Then the'rope D is fastened to the head C C, and passed over pulleys conveniently placed in the barn, and onelor morehorses attached to it, when they will easily roll it oli'.

If we wish to roll itoff for the foundation of a stack, thev rope D is passed over the top of the load, and the horses attached to the end of it, as before. If we desire to roll it on to the back side of a mow or stack, we

must pull on the ropes B B, so as to secure several feet between l'che hooks and thc edge of the rack. To do this it'nlay be necessary to let out the ropes at c c c. Itinay be observed that any length of ropes BB B may be used, provided there is room enough in the barn to usc the machine without drawing the head-piece against the pulleys. When the hooks are drawn through, as just described, they are drawn over thetop of the load and fastened in the hay, as before. The distance which the hay is rolled depends upon lthe distance which the hooks are passed over the load. The hooks will in all cases free themselves as soon as 'the hay is all rolled off p from them. Before the rolling is commenced a piece of board or scantling, or other support, should be placed under the sid of the rack over which the load is to be rolled, to prevent Vthe tipping of the rack.

By means of this machine a load may easilybe rolled on to a stack or mow which is not higher than half l the height of the load. v

l What I claim asmy invention, and desire to secure by Letters Patent, is-

The' combination of the hooks, ropes', andheadpiecle, or their mechanical equivalents, as and for the purposes hereinset forth.
